Abstract
In this paper, comparative analysis of structural dynamic responses of a damaged free-free beam has been reported. The dynamic responses evaluated in this work include the first ten natural frequencies of the damaged free-free beam and corresponding mode-shapes also. Natural frequencies and the mode-shapes of the damaged free-free beam have been compared with similar responses of geometrically similar undamaged free-free beam as well as an undamaged cantilever beam. Results show that the mode-shapes of the damaged free-free beam resemble more with the undamaged cantilever beam rather than an undamaged free-free beam. Possible reasons behind such kind of behaviour have also been discussed.
